I use Fidelity as well because of previous 401k there. These days Schwab, Fidelity or Vanguard are really all pretty competitive options. I use Schwab and Fidelity. Keep in mind, Schwab is really nice because they refund the fees on your ATM use. And free checks too. Schwab is really pretty awesome. In fact, I started using them more for investments because I felt bad about just straight up freeloading off their free ATM fees when I traveled!
